Uncle Sam is obliged to take such material for his frontier peace officers as proves itself efficient in serving processes. A coward may be highly moral, but he will not do as a border deputy. The personal character of some of the most famous Western deputies would scarcely bear careful scrutiny, but the government at Washington is often obliged to wink at that sort of thing. There came a time when it remained difficult longer to wink at the methods of the Daltons as deputies. In one case they ran off with a big bunch of horses and sold them in a Kansas town. On account of this episode, Grattan, William, and Emmett Dalton made a hurried trip to California. Here they became restless, and went back at their old trade, thinking that no one even on the Pacific Slope had any right to cause them fear. They held up a train in Tulare county and killed a fireman, but were repulsed. Later arrested and tried, William was cleared, but Grattan was sentenced to twenty years in the penitentiary. He escaped from jail before he got to the penitentiary, and rejoined Emmett at the old haunts in the Nations, Emmett having evaded arrest in California. The Southern Pacific railway had a standing offer of $6,000 for the robbers at the time they were killed.
The Daltons were now more or less obliged to hide out, and to make a living as best they could, which meant by robbery. On May 9, 1891, the Santa Fé train was held up at Wharton, Oklahoma Territory, and the express car was robbed, the bandits supposedly being the Daltons. In June of the following year another Santa Fé train was robbed at Red Rock, in the Cherokee strip. The 'Frisco train was robbed at Vinita, Indian Territory. An epidemic of the old methods of the James and Younger bands seemed to have broken out in the new railway region of the Southwest. The next month the Missouri, Kansas and Texas train was held up at Adair, Indian Territory, and a general fight ensued between the robbers and the armed guard of the train, assisted by citizens of the town. A local physician was killed and several officers and citizens wounded, but none of the bandits was hurt, and they got away with a heavy loot of the express and baggage cars. At Wharton they had been less fortunate, for though they killed the station agent, they were rounded up and one of their men, Dan Bryant, was captured, later killing and being killed by United States deputy Ed. Short, as mentioned in an earlier chapter. Dick Broadwell joined the Dalton gang about now, and they nearly always had a few members besides those of their own family; their gang being made up and conducted on much the same lines of the James boys gang of Missouri, whose exploits they imitated and used as text for their bolder deeds. In fact it was the boast of the leader, Bob Dalton, in the Coffeyville raid, that he was going to beat anything the James boys ever did: to rob two banks in one town at the same time.
